Evaluate sinA for the triangle shown
Evaluate sinA for the triangle shown - 1

Answers

Answer 1
Answer:

The value of sinA in the triangle is 0.6. Then the correct option is A.

What is trigonometry?

Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.

In the given triangle base is 8 and the perpendicular is 6 units. To calculate sinA we need hypotenuse and then use the Pythagorean theorem.

H² = P² + B²

H² = 6² + 8²

H² = 36 + 64

H² = 100

H = 10

The angle sinA is the ratio of perpendicular and hypotenuse.

sinA = P / H

sinA = 6 / 10

sinA = 0.6

Hence, the correct answer is option A.

Is the statement "line plots display individual data" true or false?

Answers

Answer:

The statement "line plots display individual data" is TRUE.

Step-by-step explanation:

A line plot provides an orderly display of all the values in a data set. It displays data as points above a number line to show the frequency of each value denoted by X. This method is a simple and quick way to organize any given data. But this is not useful for very large data set. Generally a data size of 25 to 30 entities is enough for this kind of method.

"Line plots display individual data" is a true statement

How is multiplying fractions the same as multiplying whole numbers and different

Answers

Well one similarity is that since you have to multiply, integer rules still apply and that you can also multiply variables. A difference is that with fractions, you have to make a number into an improper fraction rather than just the regular way which would most likely be the whole number with a decimal.

Answer:

Different: Because you need to make it a fraction not a whole number

Similar: Because you are both multiplying numbers

Reasoning:

The reason for this is because if you are multiplying 1/4 to 2 it equals 2/4.

But if you are multiplying 14 and 2 you don't get 2/4 you get 28.

10.25Geno had a gift card for $40. He bought a DVD for $19.50. He spent the remaining amount on two video games. To find the cost of each video game, he used the following steps.
40.00 - 19.50 = 20.50
20.50 ÷ by 2 = 10.25
each video cost

Geno now wants to write an equation to solve the problem. He let g = cost of a video game.

Which equation can be used to find the cost of each video game?
A. 2g = 19.5
B. 2g + 40 = 19.5
C. 2g –19.5 = 40
D. 19.5 + 2g = 40

Answers

D) 19.5 + 2g = 40

thats all you're asking, right?
c. 2g-19.5=40 I think i'm right

How do i find the height of an object if I only have the area, the length, and the width?

Answers

Well technicaly speaking wouldnt the width or the length be the height? Depending on what way the object is facing and is and what sides the length and width are applied to. Enjoy!=) 
area=legnth times width

normally you would subsiutte legnth for height when solving for the area of a triangle

if you have legnth, witdth, and height, then you have volume like volume of a fish tank

so
area=legnth times width
if you meant volume then if you have the area then
area=legnth times width
volume=legnth times width times height
so to solve for height when you know volume, area, legnth , width, then
divide both sides by (legnth times width or area)
volume/(legnth times width)=height
